Question | Answer |
---|---|
Epithelial tissue | covers body surfaces; lines hollow organs, body cavities, and ducts; and forms glands |
Connective tissue | protects and supports the body and its organs; binds organs together; stores energy reserves as fat; and provides immunity. |
Muscle tissue | is responsible for movement and generation of force. |
Nervous tissue | initiates and transmits nerve impulses that help coordinate body activities. |
Simple tissue | tissue with one layer of cells. |
Stratified tissue | tissue with many layers (multi-layers) of cells. |
Pseudostratified tissue | tissue with one layer of cells. Because some of the cells do not reach the surface the tissue appears multi-layered. Pseudo-False therefore this tissue is "falsely layered". |
Squamous cells | cells are flattened and scale-like |
Cuboidal cells | cells are cube shaped (square). |
Columnar cells | are tall and cylindrical or somewhat rectangular in shape. |
Transitional cells | these cells have a variety of shapes, generally larger and more rounded on the surface. They are found where there is a great degree of expansion. |
Striated tissue | the fibers (cells) contain alternating dark and light bands (striations) that are perpendicular to long axis of the fibers. |
Cilia | hair-like projections. |
Simple squamous epithelium | single layer of flat, scale-like cells, central nuclei. |
Sinple cubodidal epithelium | simple tissue, cube-shaped cell with large nuclei located in the center of the cell. |
Simple columnar epithelium | single layer of rectangular cells, nuclei are commonly oval in shape and located at the base of each cell. |
Stratified squamous | several layers of cells; squamous on surface-cuboidal to columnar in deep layers. |
stratified cuboidal epithelium | outer layer are cuboidal cells |
stratified colunar epithelium | (relatively uncommon) severaly layers of cells, columnar only on surface |
Transitional epithelium | resembles stratified squamous except superficial cells are larger and more rounded. |
pseudostratified epithelium | nuclei of cells at varying depths. Not a true stratified tissue. All cells attach at a basement membrane, in a single layer; some do not reach the surface. |
Skeletal or striated muscle | cylindrical, striated fibers with many peripheral nuclei |
smooth or visceral muscle | non-stiated fibers with one central nuclei |
cardiac or heart muscle | stiated, branching, one central nucleus and space (interclated disc) |
Hyaline cartilage | also called gristle, appears sometimes like a hoof-print. This is the most abundant kind of cartilage found in the body. |
Elastic Cartilage | contains a threadlike network of elastic fibers |
fibrocartilage | chondrocytes are scattered among clearly visible bundles of collagen fibers. |
Bone (osseous tissue) | appears like growth rings on a tree |
adipose tissue | signet ring shape with peripheral nuclei |
blood | red cells are stained pinkish gray; white blood cells are stained purple. Smaller solid dots are platelets. |
erythrocytes | red blood cells |
leukocytes | white blood cells |
neuron | cell body, dendrites (axons) and neuroglia |
